Center mass/angular velocity vector

  1. Sep 3, 2008 #1
    1. The problem statement, all variables and given/known data

    baton like figure - weight at (0,A) that has a mass M, second weight at origin (0,0) with weight 2M. These are the end points of the baton and that is it for this baton weight/location. The 2M weight has a velocity V towards the positive x axis. The goal is to locate the M mass with respect to time T.


    2. Relevant equations
    not sure....


    3. The attempt at a solution
    not sure...i think it spins in one spot... the top mass might have a velocity twice as fast...but not sure about this either...since no force then the center of mass located at (0,a/3) will stay there..but thats all i have...

    Welcome to PF!

    Hi iknowu99! Welcome to PF! :smile:

    Can you give us the full question?

    We need to know how this happened … for example, was there a sudden force along the x-axis hitting the 2M? :confused:

    that's what i thought at first but there is no force applied. the question is: provide the X,Y at time T for the mass M.
